NEW YORK (AP) -- Coming off two days of losses, U.S. stocks are mostly lower Thursday after a midday rally faded. Chemicals maker Monsanto is falling after Bloomberg News reported that U.S. authorities have concerns about its sale to Bayer. Household goods makers and smaller companies are also down, while technology, industrial and health care companies are rising. Toymakers Hasbro and Mattel are down as Toys R Us moves toward shuttering its U.S. stores.
KEEPING SCORE: The S&P 500 index fell 2 points, or 0.1 percent, to 2,747 as of 1:53 p.m. Eastern time. It climbed as much as 13 points earlier. The Dow Jones industrial average added 136 points, or 0.5 percent, to 24,891. The Nasdaq composite lost 19 points, or 0.3 percent, to 7,477. The Russell 2000 index of smaller-company stocks slid 6 points, or 0.4 percent, to 1,578, and most of the companies listed on the New York Stock Exchange traded lower.
BARGAIN HUNTING: Discount retailer Dollar General climbed $4.05, or 4.5 percent, to $93.25 after it said shoppers spent more money per trip during the fourth quarter. The company also gave a strong forecast for the year. Competitor Dollar Tree gained $1.40, or 1.5 percent, to $94.21.
TOYS WINDING DOWN: Mattel declined 38 cents, or 2.7 percent, to $13.80 and Hasbro fell $1.12, or 1.3 percent, to $87.41 as Toys R Us prepares to shut down its U.S. operations. CEO David Brandon told employees Wednesday the chain plans to liquidate all of its U.S. stores, according to an audio recording of the meeting obtained by The Associated Press. The company has 740 stores and 30,000 employees, and its struggles have hurt both Hasbro and Mattel because they each get about 10 percent of their sales from Toys R Us.
